Description

Technical Field

[0001] This invention belongs to the field of lubricating grease production technology, specifically a feeding device for lubricating grease production. Background Technology

[0002] Grease is a viscous, oily lubricant that lubricates and seals the friction parts of machinery. Currently, during grease production, a feeding device is needed to transport the tubular grease raw material to the processing chamber for processing.

[0003] Existing feeding devices can generally be divided into screw feeders or suction pump feeders. The former is used for feeding grease and requires a corresponding hopper. That is, the cylindrical grease material is manually poured into the hopper, and then the screw feeder uses a conveying pipe to transport the grease in the hopper to the processing chamber. The latter also requires manual handling when feeding grease. The cylindrical container containing the grease material is moved to the location of the suction pump, and then the feed pipe of the suction pump is inserted into the cylindrical container. The suction pump then pumps the grease into the processing chamber. It can be seen that both screw feeders and suction pump feeders require a lot of manual intervention, resulting in relatively low feeding efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a feeding device for grease production.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A grease feeding device for production includes an L-shaped support plate, a turntable, a first drive assembly, a second drive assembly, and a pumping assembly.

[0007] The pumping assembly is fixedly mounted on the side wall of the L-shaped support plate.

[0008] The turntable is rotatably mounted on the upper part of the L-shaped support plate, and is used to support several grease storage cylinders.

[0009] The first drive assembly is mounted on the upper part of the L-shaped bracket plate and is used to drive the turntable to rotate intermittently, so that the grease storage cylinder on the upper part of the turntable rotates sequentially to below the pumping assembly.

[0010] The second drive assembly is located at the bottom of the turntable. When a set of grease storage cylinders rotates to the bottom of the extraction assembly, the second drive assembly drives the grease storage cylinder to move upward, so that the extraction assembly extends into the interior of the set of grease storage cylinders to extract the grease inside the set of grease storage cylinders.

[0011] As a further improvement of the present invention: a support shaft is fixedly provided at the bottom of the turntable, and the lower end of the support shaft is rotatably connected to the L-shaped bracket plate.

[0012] The first drive assembly includes a motor, an incomplete gear, and a transmission gear.

[0013] The motor is fixedly mounted on the upper part of the L-shaped bracket plate, the incomplete gear is located at the output end of the motor, and the transmission gear is fixedly located outside the support shaft and can intermittently mesh with the incomplete gear.

[0014] As a further improvement of the present invention: the second drive assembly includes a lifting component and a piston component. When a group of the grease storage cylinders rotates to below the pumping assembly, the piston component drives the lifting component to move upward, and the lifting component lifts the group of grease storage cylinders.

[0015] As a further improvement of the present invention: the lifting component includes a holding plate and a piston rod.

[0016] The container plates are arranged in several groups, and are distributed in a ring at intervals on the upper part of the turntable to provide support for several grease storage cylinders. Several groups of piston rods are arranged in a one-to-one correspondence with the container plates. The upper ends of the piston rods are fixedly connected to the bottom walls of the container plates, and the lower ends vertically penetrate the turntable and extend below it.

[0017] The piston assembly includes a piston cylinder, a gas delivery pipe, a pressure rod, an elastic element, an annular stop block, and a piston.

[0018] The gas supply pipes, piston cylinders, and piston rods are arranged in several sets, each corresponding to a specific set. The upper ends of the gas supply pipes are fixedly connected to the bottom wall of the turntable, and the lower ends are fixedly connected to the piston cylinders. The lower ends of the piston rods extend into the interior of the gas supply pipes and are movably engaged with them. Each set of piston cylinders contains a set of pistons, and each set of piston cylinders has a set of pressure rods fixedly mounted on its sidewall. The end of each pressure rod away from its corresponding piston cylinder extends to the outside of the piston cylinder. An annular stop block is fixedly mounted on the rod body outside the corresponding piston cylinder. Each set of annular stop blocks is connected to its corresponding piston cylinder via a set of elastic elements. A rotating wheel is fixedly mounted at the motor output end, and an arc-shaped block is fixedly mounted on the circumferential sidewall of the rotating wheel.

[0019] As a further improvement of the present invention: the elastic element is a spring or a metal sheet.

[0020] As a further improvement of the present invention: a one-way bearing seat is fixedly installed on the upper part of the L-shaped bracket plate, and the lower end of the support shaft is rotatably engaged with the one-way bearing seat.

[0021] As a further improvement of the present invention: the suction assembly includes a liposuction cannula, a pump body, and a liposuction cannula.

[0022] The pump body is fixedly installed on the side wall of the L-shaped bracket plate. One end of the liposuction tube is connected to the input end of the pump body, and the other end extends vertically to an eccentric position above the turntable. One end of the liposuction tube is connected to the output end of the pump body, and the other end is connected to the processing chamber.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In this embodiment of the invention, during the feeding of grease during production, several grease storage cylinders containing grease can be placed on the upper edge of a turntable, so that the grease storage cylinders are arranged in a ring at intervals. Simultaneously, a first driving component drives the turntable to rotate intermittently, thereby causing the grease storage cylinders to rotate intermittently. When the turntable stops rotating, a group of grease storage cylinders rotates to a position below the extraction component. At this time, a second driving component drives this group of grease storage cylinders upwards, allowing the extraction component to extend into the interior of this group of grease storage cylinders and extract the grease from them. The extracted grease is then transported to the processing chamber. Thus, by using the turntable to drive the intermittent rotation of several grease storage cylinders, the cylinders are sequentially positioned below the extraction component, and the second driving component drives the grease storage cylinders below the extraction component to move upwards, thereby achieving continuous automatic grease feeding. Compared to existing technologies, this method enables automatic grease feeding during grease production, saving manpower and improving feeding efficiency. Attached Figure Description

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Please see Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a grease feeding device for grease production, including an L-shaped support plate 10, a turntable 20, a first drive assembly 30, a second drive assembly 40, and a pumping assembly 50. The pumping assembly 50 is fixedly mounted on the side wall of the L-shaped support plate 10. The turntable 20 is rotatably mounted on the upper part of the L-shaped support plate 10 to provide support for a plurality of grease storage cylinders. The first drive assembly 30 is mounted on the upper part of the L-shaped support plate 10 to drive the turntable 20 to rotate intermittently, so that the grease storage cylinders on the upper part of the turntable 20 rotate sequentially to below the pumping assembly 50. The second drive assembly 40 is located at the bottom of the turntable 20. When a group of grease storage cylinders rotates to below the pumping assembly 50, the second drive assembly 40 drives the grease storage cylinder to move upward, so that the pumping assembly 50 extends into the interior of the group of grease storage cylinders to extract the grease from the group of grease storage cylinders.

[0033] During grease production and feeding, several grease storage cylinders containing grease can be placed on the upper edge of the turntable 20, so that the grease storage cylinders are distributed in a ring at intervals. At the same time, the first drive component 30 drives the turntable 20 to rotate intermittently, which in turn drives the grease storage cylinders to rotate intermittently. When the turntable 20 stops rotating, a group of grease storage cylinders rotates to a position below the extraction component 50. At this time, the second drive component 40 drives the group of grease storage cylinders to move upward, so that the extraction component 50 extends into the interior of the group of grease storage cylinders, thereby extracting the grease in the group of grease storage cylinders and transporting the extracted grease to the processing chamber. In this way, by using the turntable 20 to drive the intermittent rotation of several grease storage cylinders, the grease storage cylinders are positioned sequentially below the extraction component 50, and the second drive component 40 drives the grease storage cylinders located below the extraction component 50 to move upward, thereby realizing continuous automatic grease feeding.

[0034] Please see Figure 1 as well as Figure 4 In one embodiment, a support shaft 201 is fixedly provided at the bottom of the turntable 20. The lower end of the support shaft 201 is rotatably connected to the L-shaped bracket plate 10. The first drive assembly 30 includes a motor 301, an incomplete gear 302, and a transmission gear 303. The motor 301 is fixedly installed on the upper part of the L-shaped bracket plate 10. The incomplete gear 302 is provided at the output end of the motor 301. The transmission gear 303 is fixedly provided outside the support shaft 201 and can intermittently mesh with the incomplete gear 302.

[0035] The motor 301 drives the incomplete gear 302 to rotate. When the incomplete gear 302 meshes with the transmission gear 303, it can drive the support shaft 201 and the turntable 20 to rotate. The turntable 20 drives a number of grease storage cylinders on its upper edge to rotate. When the incomplete gear 302 disengages from the transmission gear 303, the support shaft 201 and the turntable 20 remain stationary. At this time, a set of grease storage cylinders are located below the pumping assembly 50.

[0036] In one embodiment, the second drive assembly 40 includes a lifting component and a piston component. When a group of the grease storage cylinders rotates to a position below the extraction assembly 50, the piston component drives the lifting component to move upward. The lifting component lifts the group of grease storage cylinders, causing the extraction assembly 50 to extend into the interior of the group of grease storage cylinders to extract the grease from the grease storage cylinders.

[0037] Please see Figure 1 , Figure 2 as well as Figure 4In one embodiment, the lifting component includes a holding plate 403 and a piston rod 404. Several sets of holding plates 403 are arranged in a ring-shaped interval on the upper part of the turntable 20 to provide support for several grease storage cylinders. Several sets of piston rods 404 are arranged corresponding to each holding plate 403. The upper ends of the piston rods 404 are fixedly connected to the bottom walls of the holding plates 403, and the lower ends vertically penetrate the turntable 20 and extend below it. The piston component includes a piston cylinder 401, an air supply pipe 402, a pressure rod 405, an elastic element 406, an annular stop block 407, and a piston (not shown in the figure). Several sets of air supply pipes 402 and piston cylinders 401 are arranged corresponding to each piston rod 404. The upper ends of the air supply pipes 402 are connected to the turntable 20. The bottom wall is fixedly connected to the piston cylinder 401. The lower end of the piston rods 404 extends into the interior of the gas pipes 402 and is movably engaged with the gas pipes 402. Each set of piston cylinders 401 has a set of pistons movably arranged inside. Each set of piston sidewalls has a set of pressure rods 405 fixedly arranged. The end of each set of pressure rods 405 away from the corresponding piston cylinder 401 extends to the outside of the piston cylinder 401. The annular stop block 407 is fixedly arranged on the rod body of the pressure rod 405 located outside the corresponding piston cylinder 401. Each set of annular stop blocks 407 is also connected to the corresponding piston cylinder 401 through a set of elastic elements 406. The output end of the motor 301 is also fixedly arranged with a rotating wheel 304. An arc-shaped block 305 is fixedly arranged on the circumferential sidewall of the rotating wheel 304.

[0038] When the motor 301 drives the incomplete gear 302 to rotate, the motor 301 can also drive the rotating wheel 304 and the arc block 305 to rotate synchronously. When the incomplete gear 302 disengages from the transmission gear 303 to rotate a set of grease storage cylinders to below the pumping assembly 50, the air supply pipe 402, piston cylinder 401, and pressure rod 405 corresponding to the grease storage cylinder rotate to the side of the rotating wheel 304. As the rotating wheel 304 and the arc block 305 continue to rotate, the arc surface of the arc block 305 acts on the pressure rod 405, thereby pushing the pressure rod 405 to drive the piston to move into the corresponding piston cylinder 401, thereby compressing the air inside the piston cylinder 401 into the corresponding air supply pipe 402. After the air enters the air supply pipe 402, it pushes the piston rod 404 to move upward, thereby driving the holding plate 403 to move upward. The holding plate 403 pushes the position of the piston rod 404 to move upward. The grease storage cylinder moves upward, allowing the extraction component 50 to extend into the grease storage cylinder to extract the grease. After the extraction component 50 has finished extracting the grease from the grease storage cylinder, the pressure rod 405 passes through the middle of the arc surface of the arc block 305. At this time, the elastic element 406 pushes the pressure rod 405, causing the pressure rod 405 to drive the piston to move in the opposite direction along the inside of the piston cylinder 401, thereby drawing the air inside the air supply pipe 402 into the piston cylinder 401. This causes the piston rod 404, the holding plate 403, and the grease storage cylinder located above the holding plate 403 to move downward. The extraction component 50 moves out of the grease storage cylinder. Subsequently, the incomplete gear 302 and the transmission gear 303 mesh again, thereby driving the turntable 20 and several grease storage cylinders above it to rotate again by a certain angle, thereby adjusting the subsequent grease storage cylinders back below the extraction component 50.

[0039] In one embodiment, the elastic element 406 can be a spring or a metal sheet, and there is no limitation on this.

[0040] When the arc-shaped surface of the arc-shaped block 305 acts on the pressure rod 405, causing the pressure rod 405 to drive the piston to move along the inside of the piston cylinder 401, the arc-shaped block 305 applies a lateral thrust to the pressure rod 405. This lateral thrust is transmitted to the turntable 20 through the pressure rod 405, the piston cylinder 401, and the air supply pipe 402, causing the turntable 20 to rotate in the opposite direction. This rotation causes the grease reservoir, which was originally located below the pumping assembly 50, to shift. As the grease reservoir moves upward, the pumping assembly 50 cannot smoothly extend into the grease reservoir, thus preventing the grease from being successfully extracted. To avoid this phenomenon, please refer to... Figure 1 In one embodiment, a one-way bearing seat 101 is fixedly installed on the upper part of the L-shaped bracket plate 10, and the lower end of the support shaft 201 is rotatably engaged with the one-way bearing seat.

[0041] When the incomplete gear 302 meshes with the transmission gear 303, the support shaft 201 can rotate relative to the one-way bearing seat, thereby driving the turntable 20 and several grease storage cylinders on the upper part of the turntable 20 to rotate, so that the several grease storage cylinders rotate sequentially to the bottom of the pumping assembly 50; when the arc surface of the arc block 305 acts on the pressure rod 405 to drive the piston to move, the one-way bearing seat restricts the reverse rotation of the support shaft 201, thereby preventing the lateral thrust applied by the arc block 305 to the pressure rod 405 from pushing the support shaft 201 and the turntable 202 to rotate, so that the grease storage cylinders adjusted to the bottom of the pumping assembly 50 can remain in their original positions, so that when the grease storage cylinders move upwards later, the pumping assembly 50 can smoothly extend into the grease storage cylinders to achieve smooth grease extraction.

[0042] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment, the suction assembly 50 includes a liposuction tube 501, a pump body 502, and a fat delivery tube 503. The pump body 502 is fixedly installed on the side wall of the L-shaped support plate 10. One end of the liposuction tube 501 is connected to the input end of the pump body 502, and the other end extends vertically to an eccentric position above the turntable 20. One end of the fat delivery tube 503 is connected to the output end of the pump body 502, and the other end is connected to the processing chamber (not shown in the figure).

[0043] After the incomplete gear 302 disengages from the transmission gear 303, a set of grease storage cylinders is adjusted to a position below the grease extraction tube 501. At this time, the arc surface 305 of the arc block 304 acts on the pressure rod 405, causing the piston to move along the inside of the piston cylinder 401 to compress the air inside the piston cylinder 401 into the air delivery tube 402, thereby driving the piston rod 404, the holding plate 403, and the grease storage cylinder located on the upper part of the holding plate 403 to move upward. When the grease storage cylinder moves upward, the lower end of the grease extraction tube 501 extends into the inside of the grease storage cylinder from the upper end of the grease storage cylinder. At the same time, the pump body 502 works to pump the grease in the grease storage cylinder into the processing chamber through the grease extraction tube 501 and the grease delivery tube 503, thereby realizing automatic grease feeding.

[0044] In this embodiment of the invention, during the grease production and feeding process, several grease storage cylinders containing grease can be placed on the upper edge of the turntable 20, so that the grease storage cylinders are arranged in a ring with intervals. Simultaneously, the first driving component 30 drives the turntable 20 to rotate intermittently, thereby causing the grease storage cylinders to rotate intermittently. When the turntable 20 stops rotating, a certain group of grease storage cylinders rotates to a position below the pumping component 50. At this time, the second driving component 40 drives this group of grease storage cylinders to move upwards, causing the pumping component 50 to extend into this group of grease storage cylinders. The lubricant is then drawn from the storage cylinder and transported to the processing chamber. The turntable 20 drives several lubricant storage cylinders to rotate intermittently, positioning them sequentially below the extraction component 50. The second drive component 40 then moves the lubricant storage cylinders below the extraction component 50 upwards, thus achieving continuous automatic lubricant feeding. Compared to existing technologies, this method enables automatic lubricant feeding during production, saving manpower and improving feeding efficiency.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
